Cofepris Rules Out Salmonella in Sinaloa Jalapeños Investigated for US Outbreak

The FDA notified Cofepris and Senasica on July 31, 2026 of a Salmonella Javiana outbreak with 345 ill persons and 36 hospitalized in 27 US states, linked to jalapeños distributed by a fresh produce distributor. In response to the alert, Cofepris took samples from Mexican suppliers in Nuevo León linked to that distribution chain and, on August 15, reported that analysis did not detect Salmonella in the product investigated.

This episode illustrates an increasingly frequent dynamic in agrifood trade between Mexico and the United States: when an outbreak is detected in the destination country, backward traceability forces authorities in the country of origin to mobilize sampling resources on specific suppliers, even when the result ends up negative. That clearance exercise is not trivial: a well-documented negative result is the only way an exporter avoids prolonged suspicion while the US investigation continues.

For TAAG, the case confirms that the capacity to respond with its own analytical evidence quickly—not just wait for the result of the foreign investigation—is what allows a Mexican fresh vegetable supplier to clear itself of an outbreak detected downstream, rather than carry a suspicion that can block exports for weeks without a single sample of its own to support it.
